Abstract
An electrolyte including a dinitrile compound, a trinitrile compound, and propyl propionate. Based on the total weight of the electrolyte, the weight percentage of the dinitrile compound is X, the weight percentage of the trinitrile compound is Y, and the weight percentage of the propyl propionate is Z; where about 2 wt %≤(X+Y)≤about 11 wt %, about 0.1≤(X/Y)≤about 8, and about 0.01≤(Y/Z)≤about 0.3. The dinitrile compound comprises a compound of Formula (5): N—R—(O—R)—O—R—CN (5). The electrolyte is capable of effectively inhibiting the increase in DC internal resistance of an electrochemical device so that the electrochemical device has excellent cycle and storage performance.
